Study Notes
Producers and Consumers
- Producers are organisms that create their own food, primarily through photosynthesis.
- Consumers rely on producers or other consumers as their food source.
Photosynthesis
- Photosynthesis is the process by which plants convert sunlight into chemical energy.
- This chemical conversion involves water and carbon dioxide to produce sugars.
Chloroplasts
- Chloroplasts are specialized organelles in plant cells responsible for photosynthesis.
- They capture sunlight's energy and convert it into usable chemical energy.
Grana
- Grana consist of stacked thylakoid membranes found within chloroplasts.
- They play a crucial role in the light-dependent reactions of photosynthesis.
Chlorophyll
- Chlorophyll is the green pigment located within chloroplasts.
- It absorbs light energy needed to initiate photosynthesis.
Oxygen
- Oxygen is a byproduct of photosynthesis, essential for cellular respiration in living organisms.
- It enters the bloodstream through the lungs and is transported to body cells by the heart.
Carbon Dioxide
- Carbon dioxide is a gas that is utilized during photosynthesis and expelled by the respiratory system as waste.
